Hi @Alice, API access reflects the features available to your account, including when on-prem. APIs for Meetings, Webinars, Cloud Recording, Reporting, etc. are all available and will reflect the configuration of your account e.g. the location of cloud recording files will reflect your own account settings.
Are there particular APIs you are looking to verify access to? Please feel free to open a developer support ticket for questions directly related to your account.
My understanding is that the same APIs will be available for On-Prem accounts. If there is a specific API you’re having issues with or that you would like to double check we can definitely look into that.
